BORING OR DRILLING MACHINE.

Specification of Letters latent.

Patented Mar. 29, 1910.

T 0 all whom it may concern:

Be it known that we, VILLARD T. SEARS and HERMAN J. RUoH, citizens ofthe United States, residin at. Philadelphia, Philadelphia county,Pennsylvania, and Woodbury, Gloucester county, New Jersey, respectively,have invented certain new and useful Improvements in Boring or DrillingMachines, of which the following is a specification.

This invention, pertaining to boring or drillin machines and relatingparticularly to wor (holders therefor, will be readily understood fromthe following description taken in connection with the accompanyingdrawing in which Figure 1 is a front elevation of the main portions of aboring or drilling machine exemplifying our invention: Fig. 2 a sideelevation of the same, the bearing of one of the workholders a pearingin vertical section in the plane 0 line a of Figs. 1 and 3, and itswork-holding plate illustrated as being swung to inward normal positionand elevated together with the work-table; and Fig. 3 a horizontalsection of the machine in the plane of line b of Fig. 2.

In the drawing :1, indicates the column of the machine: 2, the verticalspindle sup ported thereby, the illustration showing the machine as beinequipped with a pair of spindles adapted for simultaneous work upon apiece: 3, the work-table, as it would usually be called but which is inthis instance merely a Work elevator; 4, a feedrack projectingdownwardly from the worktable: 5, a feed shaft to cooperate with therack in moving the work-table vertically, the rack and shaftconstituting parts of a merely typical feed device: 6, a vertical bearinrigidly supported at each side of the column: 7, a journal for each ofthese bearings, the journals and bearings bein tapering so that when thejournal is raise some dlst-ance in the bearing it is entirely freetherein: 8, a horizontal work-holding plate fast upon the upper end ofeach of the journals 7 and adapted to swing over the work-table 3: and9, an angle-plate formed on each of the work-holding plates.

The work to be operated upon is to be secured to one of the work-holdingplates 8 while that plate is swung to outward osition free of the table3, and the angle-p ates 9 if provided upon the work-holding plates, mayserve in facilitating the setting and securing of the work. While thework-holding plate is in this outer position its journal is seatednormally in its bearing. The work having been properly secured to theworkholding plate in question, and table 3 being in its lower position,the work-holding plate having the work attached is now to be swunginwardly over the table 3 so that the work will occupy proper ositionbelow the spindle or spindles. Tab e 3 is now to be elevated by means ofits feed mechanism, whereby the table engages and raises the plate towhich the work is attached and lifts the journal of that plate free ofits bearing and moves the work up into proper feeding engagement withthe tool or tools. During this upward feeding motion of the work, whichfeeding will generally be performed automatically, the vertical motionof the work will be uninfluenced by the journal of the plate carryingthe work.

l/Vhile the piece of work in question is being operated upon by themachine, another piece of work may be secured to the outwardly swungwork-holding plate upon the opposite side of the machine, the upwardfeeding motion of the machine at this time having no effect upon thissecond work-holding plate. Upon the completion of the work upon thefirst piece, table 3 is to be lowered, with the result that the journalof the active work-holding plate becomes again seated normally in itsbearing, table 3 descending clear of the plate. The plate with itscompleted work may now be swung outwardly, and the other plate with itspiece of work may be swung inwardly over table 3 and ele vated for theaction of the machine as in the previous case, and while the machine isoperating upon this second piece of work the piece of work on the firstplate may be removed and another substituted.

lVe claim:

1. A metal-working machine comprising, a tool-actuating device carriedby the upper portion of the machine, a bearing supported by the lowerporton of the machine to one side of the tool-actuating device, awork-elevating part disposed below the tool-actuating device, and awork-holding plate mounted in said bearing and adapted to swing toinward position over said work-elevating part and to swing to outwardposition free of said work-elevating part, combined substantially as setforth.

2. A- metal-working machine comprising, a tool-actuating device carriedby the upper portion of the machine, bearings supported by the lowerportion of the machine on each side of the tool-actuating device,awork-elevating part disposed below the tool-actuating device, and awork-holding plate mounted in each of said bearings and adapted to swingto inward position over said work-elevating part and to swing to outwardposition free of said work-elevating part, combined substantially as setforth.

3. A metal-working machine comprising, a tool-actuating device carriedby the upper portion of the machine, a bearing supported by the lowerportion of the machine to one side of the tool-actuating device, awork-elevating part disposed below the toolactuating device, and awork-holding plate journaled in said bearing and adapted to swing toinward position oversaid work elevating part and to swing to outwardposition free of said work-elevating part, the journal and bearing ofsaid plate being tapered so as to be free of each other when the plateis partially elevated.

4. A metal-working machine comprising, a column, a tool actuating devicecarried by the upper portion thereof, a work elevating device below thetool actuating device, and a plurality of work-holding plates supportedby the base of the column at the sides of the work elevating device andmounted for vertical motion and for angular motion on a vertical axis soas to take position either over or to the side of the work elevatingdevice.
